8 results about "Free weights" patented technology

New forms of free weights for weight training are provided. Such free weights may include a flexible, gripping ring set in a channel with a varying width, configured to be threaded over the end of a barbell. The channel may include a locking notch. Such a free weight may be rotated until the channel is aligned with a floor (perpendicular to gravity) and then loaded onto the barbell by threading the gripping ring onto the barbell. The free weight is then rotated 90 degrees causing the barbell and gripping ring to travel away from a center of the channel, where the channel narrows and includes the locking notch. The gripping ring is resultingly deformed by the narrower section of the channel entered, into an ovoid shape, gripping the barbell by force of gravity. A user may then reverse these steps, to release and unload the free weight from the barbell.

A modular and configurable muscular physical rehabilitation and training system that is a total body fitness system designed to promote strengthening and creation of muscle mass using free weights. Free weights simulate real-life situations and promote whole body stabilization. Free weights allow more variations in the range of motion than using modern machines. The system allows the flexible and configurable use of muscle contractile activities utilizing free weights and proper techniques. This is done in a space-saving, compact, safe, configurable, and practical configuration that can be used with a plurality of participants supported by a single trainer / therapist.

An intelligent weightlifting apparatus includes a frame including vertically oriented members and safety rails that are selectively moveable up and down relative to the vertically oriented members. The apparatus includes a position sensor that is configured to detect a position of a barbell. The apparatus includes a computer that is configured to control movement of the safety rails based on data from the position sensor such that a predefined distance is maintained between the safety rails and the barbell during a free weight exercise.

An apparatus for enabling a spotter to assist a lifter in a weight lifting exercise comprises a clamp for removably attaching to and enclosing a bar for free weights in an interior therein, the clamp securely retaining the bar along a length of the clamp, the bar being lifted by the lifter during the weight lifting exercise. The clamp is securely and removably attachable to a cable at an attachment end of the cable, the cable being disposed about a wheel of a pulley that is anchored to a stable point. A free end of the cable is manipulable by the spotter to selectively operate the pulley to assist with raising and lowering the bar.

An exercise apparatus including an outer handle, a rod arranged to rotate within the outer handle, a first weight plate with an opening at an upper region, and a second weight plate with an opening at an upper region, where the first weight plate is attached to the rod by a first bolt and the second weight plate is attached to the rod by a second bolt.
